   Sorry for hijacking this thread, but does that mean that you have to   
   specify an interface in ipv6 to do a link local broad/multi-cast? In ipv4   
   there is no such concept (local extensions possible), you send to the   
   broadcast address for a subnet, the ip stack figures out where to send   
   the broadcast.   
      
   Or in other words, what happens when you send to ff02::1?
